Hướng dẫn python module not found

I am a beginner with Python. Before I start, here's my Python folder structure

-project
----src
------model
--------order.py
------hello-world.py

Under src I have a folder named model which has a Python file called order.py which contents follow:

class SellOrder(object):
    def __init__(self,genericName,brandName):
        self.genericName = genericName
        self.brandName = brandName

Next my hello-world.py is inside the src folder, one level above order.py:

import model.order.SellOrder

order = SellOrder("Test","Test")

print order.brandName

Whenever I run python hello-world.py it results in the error

Traceback (most recent call last):
  File "hello-world.py", line 1, in 
    import model.order.SellOrder
ImportError: No module named model.order.SellOrder

Is there anything I missed?

All modules in Python have to have a certain directory structure. You can find details here.

Create an empty file called __init__.py under the model directory, such that your directory structure would look something like that:

.
└── project
    └── src
        ├── hello-world.py
        └── model
            ├── __init__.py
            └── order.py

Also in your hello-world.py file change the import statement to the following:

from model.order import SellOrder

That should fix it

P.S.: If you are placing your model directory in some other location (not in the same directory branch), you will have to modify the python path using sys.path.

If it's your root module just add it to PYTHONPATH (PyCharm usually does that)

export PYTHONPATH=$PYTHONPATH:

for Docker:

ENV PYTHONPATH="${PYTHONPATH}:"

you need a file named __init__.py (two underscores on each side) in every folder in the hierarchy, so one in src/ and one in model/. This is what python looks for to know that it should access a particular folder. The files are meant to contain initialization instructions but even if you create them empty this will solve it.

It's easier if you use this code

python3 -m module.sub_module

For example:

python3 -m entrypoint.settings

You need to make sure the module is installed for all versions of python

You can check to see if a module is installed for python by running:

pip uninstall moduleName

If it is installed, it will ask you if you want to delete it or not. My issue was that it was installed for python, but not for python3. To check to see if a module is installed for python3, run:

python3 -m pip uninstall moduleName

After doing this, if you find that a module is not installed for one or both versions, use these two commands to install the module.

• pip install moduleName
• python3 -m pip install moduleName

After trying to add the path using:

pip show

on command prompt and using

sys.path.insert(0, "/home/myname/pythonfiles")

and didn't work. Also got SSL error when trying to install the module again using conda this time instead of pip.

I simply copied the module that wasn't found from the path "Mine was in

C:\Users\user\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.7_qbz5n2kfra8p0\LocalCache\local-packages\Python37\site-packages 

so I copied it to 'C:\Users\user\Anaconda3\Lib\site-packages'

Just add your project root directory to environment variable: PYTHONPATH. so for the below project structure, just add Rootdir path(For e.g: add E:\Projects\Rootdir) in PYTHONPATH.

Rootdir
└── pkg2
    ├── b.py
    ├── c.py
     └── pkg2
      ├── b.py
      ├── c.py

I had same error. For those who run python scripts on different servers, please check if the python path is correctly specified in shebang. For me on each server it was located in different dirs.

I only use Python as a secondary language and probably made a newbie-error. I had similar problem and my error was calling:

import requests

I got the error

ModuleNotFoundError: No module named 'requests.adapters'; 'requests' is not a package

Turns out the file I created in the same folder named "requests.py" made a conflict. Renaming the file made it work again.

If you are using VSCode, what worked for me was I changed the interpreter of my IDE, here is a quick snapshot:

I install my packages through pip3, it appears to be like my Homebrew handles all of the packages I installed previously, so that's the tweak I had to make!!

Another solution depends on where you are running this code from.

If you try running python hello-world.py (from the src directory), you would have to do the following two things for this to work:

1. Change the import line in hello-world.py to from model.order import SellOrder
2. If not already there, add to your system environment variable. Key PYTHONPATH, value .

if you are using python 3 then try the below command. I was facing similar issue , this fixed my problem

pip3 install

I solved it by deleting previous python2 and only using python3 which is working fine on windows 10

answered Aug 12 at 15:32

you need to import the function so the program know what that is here is example:

import os 
import pyttsx3

i had the same problem first then i import the function and it work so i would really recommend to try it
